In a container, combine 3 cups flour, one egg, a packet of yeast, and about a teaspoon of salt and sugar. Also add about 3/4 cups of sour cream. Mix together and add just enough water to make dough.
Knead the dough for about 10 minutes until it gets smooth. Then place it in a greased plastic bag and refrigerate for at least 4 hours.
Fashion the dough into a large pancake and place it in hot salted oil until it is golden brown. Flip and repeat.
